Morphology

jumping + seed

The meaning 'a seed that jumps or tumbles' is directly and literally composed from 'jumping' (moving by jumping) + 'seed' (plant part), so a learner who knows both words can infer a seed that jumps. Although it is a specific botanical term, the participle+noun composition is transparent and follows common cross-linguistic patterns, making it comprehensible to a B1 learner.

Etymology

The noun jumping seed comes from small seeds that really move because a baby moth lives inside them. The moth's twitching makes the seed seem to jump, so the name came to mean a 'seed that jumps'.
